‘F’ Class 2-8-0 Locomotive class
From 1906 ten class ‘B’Explain '‘B’ Class 0-8-0 Locomotive class' goods engines were modified to have a leading pony truckExplain 'Pony Truck' the same as class ‘E’Explain '‘E’ 0-8-0 Locomotive class', but were also fitted with larger 5ft 2in diameter boilersExplain 'Boiler'. From 1911 these engines became known as class ‘F’. In addition, two class ‘E’ engines also received the larger boiler and thus brought the number of class ‘F’ engines up to twelve. View more details
‘G’ 0-8-0 Locomotive Class
Mr WhaleExplain 'Whale, George (1842—1910)' converted ‘B’ classExplain '‘B’ Class 0-8-0 Locomotive class' four-cylinder compoundsExplain 'Four Cylinder Compound' into ‘G’ class two-cylinder simple engines, retaining the ‘B’ class’s inside frame low-pressure cylinders. As these cylinders were 1in larger in diameter he reduced the boiler pressure to 160 psiExplain 'PSI (Pounds per Square Inch)' so the tractive effort would be about the same. The distinctively shaped covers below the smoke box were retained even though they had nothing to cover. These covers lead to the nickname ‘piano front Gs’. View more details
‘G1’ 0-8-0 Locomotive Class
Super heatedExplain 'Super Heated Steam' 0-8-0, some built new, but 279 rebuilt from classes ‘A’ to ‘G’. The main external difference compared with a ‘G’ class is the longer smoke boxExplain 'Smoke Box', to accommodate the super heater headerExplain 'Super Heater Header', though the barrel length of both boilersExplain 'Boiler' was the same at 14ft 10in; internally inside-admissionExplain 'Inside Admission Valve' piston valves replaced the ‘G’ class slide valvesExplain 'Slide Valve', though the cylinders were the same size. They were originally fitted with super heater dampersExplain 'Super Heater Dampers', they were soon found to be unnecessary and so removed. At some stage, possibly after first World War, steam heatingExplain 'Steam Heating' was added also, not so much for passenger trains, as for working banana specials from Garston Docks. Some 25 specials might be run at short notice when Fyffe’s steamer came in. View more details
‘G2’ 0-8-0 Locomotive Class
In 1921-2 sixty class ‘G2’ 0-8-0s were built. They were a development of the ‘G1’ classExplain '‘G1’ 0-8-0 Locomotive Class' with higher boiler pressure, 175 psiExplain 'PSI (Pounds per Square Inch)' (compared with 160 psi). The ‘G2s’ were the only LNWR 0-8-0s which were never rebuilt to some other class, and none were ever painted in lined livery. View more details
‘G2A’ 0-8-0 Locomotive Class
October 1935 ‘G1’ classExplain '‘G1’ 0-8-0 Locomotive Class' converted like ‘G2’ classExplain '‘G2’ 0-8-0 Locomotive Class', with higher boiler pressure, stronger motion and increased brake power. View more details
George the Fifth 4-4-0 Locomotive Class
A class of 4-4-0 locomotives built by Bowen CookeExplain 'Bowen Cooke, Charles J (1859—1920)' from 1910, a superheatedExplain 'Super Heated Steam' development of Whale’sExplain 'Whale, George (1842—1910)' “Precursor” classExplain 'Precursor 4-4-0 Locomotive Class (2)', and named after the first of the class. Initially “Queen Mary” (the second in the class), was built without superheating, for comparative trials with its sibling. Following the trials later members of the class were built superheated and “Queen Mary” was also converted. Engines of the class probably performed more prodigious feats of hauling heavy trains at high speeds than any other 4-4-0.
Greater Britain 2-2-2-2 Locomotive Class
This class of ten 2-2-2-2 compoundsExplain 'Compounding' was built by WebbExplain 'Webb, Francis William (1836—1906)' from 1891 to 1894. With 7ft driving wheelsExplain 'Drive Wheel' and the same cylinder arrangement and valve gearExplain 'Valve Gear' as the “Teutonics”Explain 'Teutonic 2-2-2-0 Locomotive Class', they were a massive development of that class. Their overall length, at just over 54ft, was comparable with that of the eight-coupled goods engines. All had two-word names; each word on its own name plate on each splasherExplain 'Splasher'.
